Discovering megacities is not her style but getting lost in tiny coastal villages, capturing the beauty of the sea while snorkeling. Wherever she goes, she takes her mask, fins and underwater camera with her. She has a big interest in exploring the world’s last hidden underwater paradises and marine conservation. She hopes to inspire people to protect our oceans by sharing her underwater stories. Find her photos on @anett.szaszi Instagram too!
